Occt power test. Something wrong? Maybe 14900kf needs setting up in bios, anyone got the right settings to help?

Can someone tell me a guide on how to properly set the voltage according to intel for my 14900kf, I'm getting loads of crashes and erros when I do a power test, when I finish a power test my pc blue screens. And my 14900kf reaches 100oc in a power test and when I click finish I receive the blue screen as the temperatures are dropping and occt crashes and instability begins for a bit…. could be a blue screen or random application crashes even when I'm not using occt, like doing something random web surfing or playing games… If anyone can help, would be much appreciated. I've tried rolling back drivers for gpu, reinstalling windows, drivers etc, and usb install to delete partions and start again, still getting problems.

I'm on 14900kf, 32gb ram 6200mhz, rtx 4080super, z790 aorus ice ax motherboard board.
